I am currently working with the PCAN-USB FD device and trying to initialize CAN-FD communication using the PCAN Basic API. However, I am encountering the error "Error with initializing CAN interface: 0x1400".
I have also reviewed the configuration and ensured that both the nominal and data bitrates are set correctly in PCAN-View.
I have attached the code and screenshot,
